Abstract: The trip caused by the leakage and flick in the connections of measuringtubes often happened. Several connection methods commonly used in measuringtube installation were presented; the matters needing attention in selection of different measuringtube connection method were pointed out. It is expected that this paper can provide the reference for design and installation of sequent generation units.
